15 20 25 511 824 FIGURBESKRIVNING Uppfinningen beskrives nämnare nedan under hänvisning till bifogade ritning, på vilken Pig. 1 är en partiell tvärsektionsvy av en chipsmodul som innefattar en utförings- form av en avkopplingskondensator enligt uppfinningen och Pig. 2a-2c är vyer längs linjen A-A i fig. 1 av olika utföiingsforrner av den ena plat- tan i avkopplingskondensatorn enligt uppfinningen. 511 824 DESCRIPTION OF THE DRAWINGS The invention is described in more detail below with reference to the accompanying drawing, in which Pig. 1 is a partial cross-sectional view of a chip module incorporating an embodiment of a decoupling capacitor according to the invention and Pig. 2a-2c are views along the line A-A in fi g. 1 of different embodiments of one plate in the decoupling capacitor according to the invention.
DETALJBESKRIVNING AV UPPFINNINGEN Fig. 1 är en partiell tvärsektionsvy av en chipsmodul med en avkopplingskondensa- tor enligt uppfinningen.DETAILED DESCRIPTION OF THE INVENTION Fig. 1 is a partial cross-sectional view of a chip module with a decoupling capacitor according to the invention.
Chipsmodulen enligt fig. l innefattar ett jordplan 1, ett skikt 2 av dielektriskt mate- rial på jordplanet 1 och ett chips 3 som är anordnat i ett uttag i det dielektiiska skiktet 2.The chip module according to fi g. 1 comprises a ground plane 1, a layer 2 of dielectric material on the ground plane 1 and a chip 3 arranged in a socket in the dielectric layer 2.
En kondensatorplatta 4 i enlighet med uppfinningen är inbäddad i det dielektiiska skiktet 2 på avstånd från jordplanet 1 och bildar en avkopplingskondensator med jordplanet 1.A capacitor plate 4 according to the invention is embedded in the dielectric layer 2 at a distance from the ground plane 1 and forms a decoupling capacitor with the ground plane 1.
Kondensatorplattan 4 enligt utföringsformen i fig. l har två anslutningsklärrirnor 5 och 6, vilka sträcker sig från plattan 4 till det dielektiiska skíktets 2 ovansida. An- slutningsklärnman 5 är bondad till en klämma (icke visad) på chipset 3 medelst en bondningstråd 7, medan anslutníngsklämrnan 6 är ansluten till en ledare eller an- slutningsplätt 8 på det dielektriska skiktet 2.The capacitor plate 4 according to the embodiment in fi g. 1 has two connection clearers 5 and 6, which extend from the plate 4 to the upper side of the dielectric layer 2. The connection terminal 5 is bonded to a clamp (not shown) on the chip 3 by means of a bonding wire 7, while the connection terminal 6 is connected to a conductor or connection plate 8 on the dielectric layer 2.
I fig. 2a-2c visas tre olika utföringsforiner av den i det dielektiiska skiktet 2 inbäd- dade kondensatorplattan. Gemensamt för de i fig. 2a-2c visade utföririgsforrnenia är att kondensatorplattorna är avsmalriande i riktning mot anslutningskläniinan 5, som är bondad med chipset 3 via bondriingstråden 7. .| l 10 15 20 511 824 I fig. 2a visas en kondensatorplatta 4” med triangulär form, medan fig. Zb visar en kondensatorplatta 4” med solfjäderform och fig. 2c visar en kondensatorplatta 4”' med trappstegsformade sidor.I fi g. 2a-2c show three different embodiments of the capacitor plate embedded in the dielectric layer 2. Common to those in fi g. 2a-2c is that the capacitor plates are tapered in the direction of the connection terminal 5, which is bonded to the chip 3 via the bonding wire 7.. l 10 15 20 511 824 I fi g. 2a shows a capacitor plate 4 ”with a triangular shape, while fi g. Zb shows a capacitor plate 4 ”with fan shape and fi g. 2c shows a capacitor plate 4 "'with stepped sides.
Andra former torde vara uppenbara för fackmannen så länge som det generella kra- vet pâ att kondensatorplattan skall vara avsmalnande är uppfyllt.Other forms should be apparent to those skilled in the art as long as the general requirement for the capacitor plate to be tapered is met.
Det är underförstått att den andra plattan i kondensatorn inte nödvändigtvis behöver vara ett jordplan i en chipsmodul, utan kondensatorn kan vara en diskret komponent med den ena eller båda plattorna avsmalnande.It is understood that the second plate in the capacitor does not necessarily have to be a ground plane in a chip module, but the capacitor may be a discrete component with one or both plates tapered.
Genom att göra minst en av kondensatoms plattor avsmalnande i enlighet med upp- finningen kommer växelströmskomponenter av olika frekvens att avkopplas på olika avstånd från anslutningsklärrnnan.By tapering at least one of the capacitor plates in accordance with the invention, AC components of different frequencies will be disconnected at different distances from the connection terminal.
Genom att placera den avsmalnande kondensatorplattan 4 med sin spets, dvs anslut- níngsklännnan 5, mot chipset 3 såsom visas i fig. 1, kommer växelströmskompo- nenter av högre frekvenser att avkopplas närmare chipset 3 än växelströmskompo- nenter av lägre frekvenser.By placing the tapered capacitor plate 4 with its tip, ie the connection dress 5, against the chip 3 as shown in fi g. 1, higher frequency AC components will be disconnected closer to the chip 3 than lower frequency AC components.
Det skulle givetvis även vara möjligt att vrida kondensatorplattan l80°, varigenom växelströmskomponenter av lägre frekvenser skulle avkopplas närmare chipset 3 än växelströmskomponenter av högre frekvenser.Of course, it would also be possible to rotate the capacitor plate 180 °, whereby lower frequency AC components would be disconnected closer to the chip 3 than higher frequency AC components.
Såsom torde framgå av det ovanstående erhålles med hjälp av avkopplingskonden- satorn enligt uppfinningen en enklare lösning på problemet med att avkoppla växel- strömskomponenter av olika högfrekvenser.As will be apparent from the above, with the aid of the decoupling capacitor according to the invention, a simpler solution to the problem of decoupling alternating current components of different high frequencies is obtained.
